CARBURETER.

' erence being had therein to the accompanying drawing.

This invention relates to certain new and useful lmpr'ovements 1n carbureters, the object'being to provide a carbureter which is exceedingly simple and cheap in construction and one which is so constructed that the flow of oil and air is'regulated by the throttle valve.

Another object of the invention is to provide a carbureter with a removable water jacket in order to thoroughly heat the mixture passing through the outlet passage to the engine cylinder so as to volatilize the 'mixture broken up by the fan which is revolved by the suction of the engine;

A further object of the invention is to provide a novel form of inlet nozzle for controlling -the liquid fuel to the carbureter which is under the control of the operator and adjusts itself as the throttle is opened and closed in order to increase and decrease the flow of oil.

A still further object of the invention is to provide a locking'device which is automatically partially locked when the throttle is closed, thereby preventing anyone from starting the engine to which the carbureter is attached without first working the combination controlling the locking device.

Another object of the invention is to provide a carbureter which is controlled by manually shifting the throttle valve and one in which the parts are so mounted and arranged that an exceedingly strong and durable carbureter is formed.

Other and further objects and advantages of the invention will'be hereinafter set forth and the novel features thereof defined by the appended claims. i

the clutch faces; Fig. 5 is a plan view of one of the knob dials; and Fig. 6 is a plan view of the other knob.

Like numerals of reference refer to like parts in the several figures of the drawing.

In the drawing, 1 indicates a casing forming the' body of my improved carbureter which is provided with an open end over which is arranged a cover 2 having a central tubular portion 3 forming the outlet. passage, said tubular portion being adapted to be formed integral with the cover and the manifold which is connected to the engine.

in the ordinary manner. The outlet passage formed by the tubular portion is provided with a throttle valve 4 having an outwardly projecting stem 15 which is mounted in a boss 6 formed on the side of the casing and is provided with a crank 7 to which the throtthe Water jacket detached in order; to repair the same when desired and it will be seen .that the passage through which the explos sive mixture passes will be maintained at an even temperature in order to thoroughly heat the mixture to produce the best results.

An interiorly threaded depending boss 12 is formed in the bottom of the casing 1 in which is threaded an L-inlet pipe 13 which is adapted to be connected to any suitable source of supply and said pipe extends upwardly into the casing 1 and is provided with a conical seat 14 at its upper end for the purpose later described. The passage of the inlet pipe is enlarged to form a chamber as shown at 15 and the upper end of the pipe isprovided with a bore of a larger diameter than the bore at the lower end through which extends a nozzle 16 which comprises a tube X having a conical point forming the nozzle is provided with perfora the inflowing 'oil to all parts of the mixing chamber formed by the casing. The upper end of the tube X carries a rod 20 which extends through a bearing 21 and on which is adjustably mounted a dispersing fan 22 secured in its adjusted position thereon by a screw 23, said fan having reticulated blades of such a shape that the same will be rotated by the suction of the engine so as to thoroughly mix the air and liquid hydrocarbon.

The wall of the casing is provided with an air inlet passage 24 in which is mounted a butterfly valve 25 carried by a stem 26 on which is secured a crank 27 to which the' lower end of the connecting link 11 is pivotally connected whereby said valve will be opened and closed simultaneously'with the throttle valve. Secured on the outer ends of the stem 26 are collars 28 formed on the ends of the bracket arm 29 which is provided with a yoke 30 in which is pivotally mounted a collar 31 carried by a sleeve 32 fixed on the tube X in order to raise and lower the tube as the air inletvalve is opened and closed. As the tube is raised, it will be seen that the spray nozzle formed on its lower end will be drawn upwardly in.

order to allow the liquid fuel contained therein to be sucked outwardly into the chamber in which it is mixed with air mixing chamber is regulated simultaneously with the opening and closing of the throttle and air inlet valve whereby the proper proportion of air and oil will be admitted to the carbureter in order to obtain the best result without adjusting the same;

To prevent anyone from opening the valves of the carbureter after the throttle has been closed, I provide a locking device which comprises a disk 33 having beveled edges 34 and oppositely disposed notches 35 adapted to receive the beveled heads 36 of spring members 37 carried by the beveled gear 38 fixed on the tube X which allows the same to be drawn upwardly. As the tube is forced downwardly, the beveled heads ride over the beveled edges of the disk and engage the underside of the same in order to prevent the upward movement'ofthe tube, the disk being fixed to the inlet L which is locked in its adjusted position within the casing by a nut 39. The beveled gear 38 is provided with a central collar havin a ratchet face 40 which co-acts with a rate et face 41 of a sleeve 42 slidably mounted upon thetube X, said sleeve being provided with a transverse slot in horizontal alinement with an apertured bracket 43 carried by the casing in which is slidably mounted a shaft- 44, the end of which is adapted to enter an opening 45 formed in the tube X to prevent the upward movement 'of the tube. The shaft 44 is slidably mounted within a tubular shaft 46 which, in turn, is mounted with a bearing 47 formed in the wall of the easingl, said casing having a housing 48 provided with a pivoted cover 49 having a suitable lock 50. By providing the housing with .a lock, the operating mechanism of the locking device, as will be later described, is inclosed' in'order to prevent anyone from tampering with the same. -The outer end of the shaft'46 is provided with a cylindrical in order to hold the same in extended position into the opening'of the tube X. The

outer end of the shaft 44 is provided with a graduated dial knob 54 and keyed on said .shaft is a pinion 55 which is adapted to mesh with a rack 56 formedon the sleeve 42 sc that by rotating. said shaft, the sleeve 42 can be raised and lowered upon the tube X in order to throw the teeth 41 into and out of engagement with the teeth 40 of the beveled gear 38. By this construction, it will be seen that the sleeve-is raised above the beveled gear in order to allow the same to be rotated and moved upwardly. In this position, the gear is prevented from being moved upwardly by the spring members 37 andin order to rotate the gear to throw the spring members into vertical alinement with the notches of the disk 38, Iprovide the shaft 46 witha beveled gear 57 which is adapted to be normally held out of mesh with the beveled gear by a coiled spring 58. The outer end of the shaft 46 is provided with a graduated turn dial 59 and by rotating the shaft 46, after the beveled pinion has been forced into engagement with the beveled gear, the 'gear' will be rotated until the spring members are brought into vertical raised so as to throw the notches of the disk out. of alinement with the spring arms, it is necessary to know the number of turns to give the dial 59 in order to release the tube X after it has been forced into position as the spring arms ride over the beveled disk and the casing, I provide the same with a drain-,

cock (30 which is so constructed, that the contents of the mixing chamber can be removed. -After the carbureter has been once adjusted, it is never necessary to readpist the same as the proper amount of oil and air is admitted simultaneously to the mixing chamber by shifting the throttle valve.

The tube X is rovi'ded with a valve 61 atthe junction 0 the spray nozzle which.

co-acts with the conical seat of the inlet pipe in order to' form a double seal, therebypreventing any surplus of oil which may accumulate within the chamber 15 from being sucked into the mixing chamberafter the supply has been out OE and it Wlll also be seen that this valve 61 is conical in form in order to scatter the oil sucked out of the nozzle by v the suction of the engine. As the valves carried by the tube X are raised off of their seats, it will be noticed that the 7 fan is moved within the outlet opening-so that the air and gas will be contracted to a" certain extent before it reaches the fan where it will be thoroughly mixed by the rotation of the fan as the mixture passes the same. As the fan is moved upwardly it is, of course, understood that the throttle valve and air valve are simultaneously opened in order to allow the proper amount of explosive mixture to be drawn into the engine through the manifold, not shown, which is; formed integral with the central tubular eportion of the cover.

Fromg the foregoing description, it will be seenv that I have provided a carbureter which is so constructed'that after the same has been installed in an engine, no further attention is necessary, the parts being so mounted and operated that the proper amount of oil and air will be admitted to the mixing chamber and discharged therefrom through an outlet whichis surrounded by a water jacket having an inlet and out let by means of which hot water can freely circulate therethrough in order toheat the combustion mixture, the fan agitating the mixture so that as it enters the engine, it will be in proper condition to obtain the best results. While I havedescribed acarbureter especially adapted for use with gaso-' lene, it "can be used for carbureting any liquid desired... v

In the-operation of the locking device for the carbureter, when the valves are;

2. A carbureter" moved into closed position, the arms. 37 with the heads 36 ride over the bevel edge. 34 of the disk 33 and. effect a partial looking automatically of the valves. The sleeve 42 is then forced .downwardly into engagement with the ratchet face 40 upon the bevel gear 38 which preventsthe gear, car rying the arm 37, from rotating and forms a positive lock for the valves so that it is necessary tofirstraise the sleeve 42 through the medium of the shaft 44; in order to allow the gear 57,.to operate the gear38 n order to turn the arms 37 so asto bringthe bevel heads into register withthe notches of the disk 33 and the spring58 will then force the gear 57- out of mesh'wi-th the gear. 38 so that the valves can be moved into open position. v I
